Thriller films use suspense, tension, and excitement to stimulate the viewer's emotions and create anticipation, expectation, uncertainty, and anxiety. They tend to have fast-paced, gritty plots. Horror films aim to elicit negative emotions from viewers by playing on primal fears using scenes that startle and themes involving the macabre, supernatural, and viewers' nightmares. Psychological thrillers emphasize the unstable psychology of complex characters and incorporate elements of mystery, drama, horror, and psychological horror to explore moral ambiguity and dissolving realities.

2. Thriller is a broad genre of literature, film, and television programming that uses
suspense, tension and excitement as its main elements. Thrillers heavily stimulate the
viewer's moods, giving them a high level of anticipation, ultra-heightened
expectation, uncertainty, surprise, anxiety and/or terror. Films of this genre tend to be
adrenaline-rushing, gritty, rousing and fast-paced.

3. An action work will generally have a fast-paced, centred, and definite plot. It
generally adheres to the hero cycle faithfully, and its plot revolves around character
development. Action is inclined toward third person narration, although first person
narration is not unusual. Action works are also generally down-to-earth works, even
though their premise may be fanciful.

4. Horror is a film genre seeking to elicit a negative emotional reaction from viewers
by playing on the audience's primal fears. Horror films often feature scenes that
startle the viewer; the macabre and the supernatural are frequent themes. And
they may overlap with the fantasy, supernatural, and thriller genres. Horror films
often deal with the viewer's nightmares, hidden fears, revulsions and terror of the
unknown. Plots within the horror genre often involve the intrusion of an evil
force, event, or personage, commonly of supernatural origin, into the everyday
world. Prevalent elements include ghosts, vampires, werewolves, demons, vicious
animals, monsters, zombies, cannibals, and serial killers. Conversely, movies about
the supernatural are not necessarily always horrific.

5. Psychological thriller is a fictional thriller story which emphasizes the
psychology of its characters and their unstable emotional states. In terms of
classification, the category is a sub-genre of the broader ranging thriller
category,[with similarities to Gothic and detective fiction in the sense of
sometimes having a "dissolving sense of reality", moral ambiguity, and
complex and tortured relationships between obsessive and pathological
characters. Psychological thrillers often incorporate elements of
mystery, drama, and horror, particularly psychological horror. They are
usually books or films.
